IMPROVED BALANCE PRESSURE-REGULATOR FOR STEAM, WATER, 0R GAS.

Specification forming part ot' Letters Patent No. 35,104, dated April 29, 18th.

To all 107mm t may concern:

Be it known that I, ENooH Oseoon, of Boston, county ot' Suffolk, and State ot MassaM ehusetts, have invented a new and uset'ul Improved Regulator for Regulating and Balancing the Pressure ot' Steam, lVater, Air, or Gas, as desired; and I do hereby declare the following to be a tfnllv and exact description thereot', reference being had to the accompanying drawings and letters ot re'lerenee in arked thereon ll `igure l is a vertical sectional view ol' my invention, showing all its parts and their operation; liig. 2, a longitudinal elevation; Figs. 3, Couplings; Fi 4- 4, valve and valveseat.

I do not elaiin the arrangement made with a large iron eap and a very small beveled valve connect-ed together by a stitlE rod, the eap set in mercury and weighted to open the valve to let the gas pass into the regulator through the valve instead ot out through it for use, `for that has been tried and tound useless.

The nature ot' my invention eonsists iu the applieation and eombination of a valve and a diaphragm a little larger than the valve or their equivalent arranged and eonneeted together to operate :'lgaiust eaeh other to hold and balance any pressure that may come against them, the gas eoming in between them and out through the valve into the chamber below it for use, as shown in the drawings.

rlhe followin is a description and illustration of my invention.

A A represent a tube, box, or pipe for the steam, water, air, or to pass through for use; B, outlet on the upper side and end covered with a liexible diaphragm, D. At the other end, on the under side, is a valve, E, with sharp square edges, and hung by its pintle F on a hook on the lower end ot' wire (i, the end of said wire passing up througli the diaphragm and a dish that is on it, and fastened to them b v a nut above and liielow them, screwed to them gas-tight, connecting the "alve and diaphragm together. For steam, piston-heads maybe used. The diaphragm, being somewhat larger than the valve E, gives it power to elose it. Thus when the gas passes into the regulator between the valve and diaphragm, the valve will be closed, because more surface is exposed to the pressure ot' the gas by the increased size ot' the diaphragm over that of the valve. By putting weights into the dish attaehed to the iliaphragm I can, more or less, equalize the excess of pressure on the diaphragm, so that the valve will open as much as desired and allow the gas to pass out through it into the ehamber below it for use, and the pressure in the chamber below the valve from which the is used is regulated as desired by the amount of weight plaeed in the pan on the diaphragm, the weights balancing to the degree required the excess of pressure gained upon the diaphragm by its increased size over the valve and regulating the pressure in the chamber below the valve without regard `to the amount of pressure in the chamber between the valve and the diaphragm, whether the pressure be one or ten pounds. It the gas is withdrawn from the chamber under the valve, the power ot' the weights on the diaphragm will be exerted to open the valve until a sufficient amount of gas eau pass through to again establish the original equilibrium, and there being no frietion the action is immediate and steady and the result Certain. Then the pressure is not being removed troni the chamber under the valve, the pressure between the valve and diaphragm and below the valve will ol' Course become the same, and the excess otf size in the diaphragm will cause the valve to elose, thus making a selt-regulator of the pressure,' and saving from twenty ive to thirty-iive per Cent. of gas with the same light.

By this regulator water for running factories and mills can be regulated as easily as steam is now regulated tor the same or any other purpose.

Il is a bar aeross the valve-seatto guide the valve; I, valveseat, beveled; J, serew through whieh to remove the Coal-tar or any other impu rities or obstruction.

I do not elaim the largeiron Cap inmereury, weighted and eonneeted by a stiff rod to a small valve to open it to let the pass into the regulator through [he valve instead ot' out through foruse, tor that is useless; but IVhat I do claim, and desire to secure by Letters Patent, is-

The Combination of a valve and a diaphragm enough larger than the Valve to give it any operate desired power over it Wanted to Close it to hold and balance any pressure that may come in between them, to be Weighted out by Weight-s on the diaphragm to give the desired pressure Wanted in Jdie Chamber below the Valve for use, constructed and connected together to against each other, substantially as and for the purpose herein described.
